Kanetsugu Saiun Series SD-04 Santoku 170mm (6.6 inch)

Availability: Normally ships the same day

Saiun Damascus knives have a cutting edge of VG-10 stainless steel that is clad with Damascus (Total of 33 layers; HRc. 60-61) and use Kanetsugu’s special convex edge profile to provide outstanding cutting performance and excellent edge retention. A comfortable black linen Micarta handle accentuated the wood-grain pattern of the Damascus and is shrink-proof, very durable and water-resistant. The stainless steel bolster improves the blade balance and durability and looks stylish next to the red fiber spacer. Kanetsugu use all their passion and experience to make certain that these extremely beautiful knives are still exceedingly practical and cut exceptionally well.

The tall blade and rounded nose / tip of the Santoku make it a versatile knife that is well suited to cutting meat, fish, or vegetables; Hence it’s name, which literally means “Three-purpose”. The Santoku is often recommended as a multi-purpose kitchen knife.

We believe the quality and cutting performance of Japanese knives are the best in the world, and hope you enjoy fine craftsmanship and sharp edge with your new knife. With proper cares, every Japanese knife should be your special cooking partner for long times.


This is the Stainless steel blade kitchen knife that has a good rust resistance for easy maintenance. However, it may get rust, if kept in wet condition.

  • Please do not put the knife in the dishwasher machine for cleaning.
  • Please do not leave the knife in water or wet condition for long time.
  • After using, please hand wash the blade, bolster and handle thoroughly, and wipe it clean and dry with soft clothes, and keep it in dry place.
  • This is an extremely sharp knife. Please use special cares in using and storing it.
  • Unlike German made knives, Japanese knife blades are ground to thin cutting edge for sharper cutting and easier re-sharpening. Please protect the edge from hitting hard materials to avoid chipping or cracking.
  • Please do not use it to cut bone or frozen foods, any hard shell foods such as lobster and crab.
  • We recommend using Japanese whetstones to re-sharpen the knife, when it gets dull.

High quality, well-balanced, versatile and beautiful knife. VG-10 steel seems to be a good compromise between lasting sharpness and ease of maintenance. Excellent price-quality ratio. In addition, delivery was efficient.

A great knife

This is a gorgeous, fabulous knife. It has a big, comfortable handle that grips securely. It's well-balanced, razor-sharp, and hefty. It's almost effortless to use. This Kanetsugu is a fantastic knife at a great price.

Kanetsugu Saiun Series SD-04 Santoku 170mm (6.6 inch)

Très bon couteau, et très belle lame. Cependant juste un petit reproche, je m'attendais a ce que le couteau soit beaucoup plus affûté. Mais il l'était tout de même relativement bien. J'aurais voulu qu'il soit affûter comme un rasoir. Perfectionniste ? Very good knife, and very nice blade. However just a small complaint, I expected the knife to be much sharper. But it was still relatively good. I wanted it to be sharpened like a razor. Perfectionist ?

Kanetsugu Saiun Series SD-04 Santoku 170mm (6.6 inch)

Hello! I am very pleased with the knife. Good cut, imprisoned, as you recommended by 12 degrees. Doesn’t get much to the stated hardness. Heavy is 226 grams! I would like it easier. I will definitely recommend it to friends for purchase. My next purchase from you will be something of R-2 steel. Best regards, Georgiy.
